While statement and Pipe

[HopeLessGuy]

I currently have a while loop which reads the file till EOF. The file contains file names that are to be searched. In the while statement, I noticed that korn shell does not treat the pipe, | , as it original is used.

For example -

while read tmpFiles
do
i=$i+1
tmpArray=$tmpFiles
fName="${tmpArray}"

grep -c "yo" ${fName%% *} | awk -F: '$2 == 3 { print $1 }'

done < &quot;tmpList.dat&quot;

That's just rushed code, shouldn't be taken into account But I noticed, that while the loop executes. It will read the right side of the pipe ( | ) then read &quot;tmpList.dat&quot; then read the left side of the ( | ). Therefore the awk is useless since it doesn't receive the exact information from grep due to the order of execution. If I were to use the grep | awk out of the loop, it works. Any ideas?

I don't think the problem stems from execution order or anything odd like that, but because of the grep -c output format.

With multiple files, e.g. grep -c yo file*, it looks like this:

[tt]file1:3
file2:0
file3:3[/tt]

But with a single file, e.g. grep -c yo file1 it looks like this:

[tt]3[/tt]
